Hold onto your mascara, y'all.

Everything was perfect. The song, the décor; his suit, her dress. If only the setting—and the circumstances—had been different.

A video of an emotional daddy-daughter dance inside an Atlanta hospital room is moving the masses. Last week, Christina Thompson shared a clip of her two-year-old daughter Phoenix, who is being treated for acute myeloid leukemia at the Aflac Cancer & Blood Disorders Center of Children's Healthcare of Atlanta, enjoying a special moment with her father Brett.

According to her GoFundMe page, little Phoenix was diagnosed with leukemia on August 2, 2018. She began aggressive chemotherapy two days later and is set to undergo four rounds of chemo within the next five months.

Suspecting she and her mom needed some cheering up, Brett plotted with her nurses to deliver a dress for each of them to Phoenix's hospital room.

"Today on Phee's last day of chemo on her first round and Daddy came to visit. Little did we know he had some surprises for us," Christina captioned the touching video on Facebook. "I mean honestly I don't think I could have picked a better man for my kids. At 2 years old this is hard on her on her family and the people that love her."

"Brett thank you for being just what our children need," the post concluded. "Did I mention she really loves her daddy."

You can donate to Phoenix's treatment here, and while you're at it, please pass the tissues.
